About This GMC SIERRA 3500HD

This 2026 GMC Sierra 3500HD is a heavy-duty pickup built for serious work with minimal use, showing just 56 miles. Finished in white with a four-door crew cab configuration, it offers the strength and durability expected from a one-ton truck while maintaining a refined interior setup.
Power comes from a 6.6-liter Duramax diesel engine paired with an automatic transmission, delivering the torque and reliability required for towing, hauling, and commercial applications. The pickup body style makes it well-suited for jobsite use, equipment transport, or heavy-duty personal needs.
Inside, the brown leather interior provides a comfortable and upscale environment, combining durability with everyday comfort. With its near-new condition and heavy-duty drivetrain, this Sierra 3500HD is work-ready and built to handle demanding tasks with ease.
